Well, the Betta fish caught my eye one day at Wal Mart when I was leisure shopping.
They were really pretty so I decided, heck, why not get one.
So I bought one, a blue veil tail, and named him Dumbledore.

Now, Dumbledore is a very curious fella. He is always swimming to the edge of the tank, and staring at my room. And whenever I walk by he swims up tp me and looks at me. He recognized me as being his owner the day after I got him. He's only flared his fins at me once, mainly because I guess I scared him getting up in the dark. But regardless. He is sweet and very active.

Ok, I have another fish her name is opal and she is really tiny,
I was at petco and I was looking at all the fish all the males had fantastic arrays of many colors and the females had vibrant colors pretty faces, but I saw the tiniest female there she was basically colorless, and was helpless but, I loved her
in spite of all the others I picked her.

About funny personalities. A few of my bettas make bubble nest all the time. And a few i have never do that.But i have one betta which somehow have those huge bubbles,which does not look like bubble nest. He keeps staring at the bubble long long ….time until i distracted him. And while he stares at it his body go to the right and to the left. It kind of remind to me my dog when she listen to me and tilt her head . It just hilarious to me. His bowl is on the table where we eat so we see him all the time.

And here is my last fishy, Angel, I was
in petco and was looking at all the delta and halfmoon males
they all were so pretty but I could not take my eyes off of this one,
he is my fish with one of the strongest personalities!
